Our sampling systems are designed to comply with <strong>API 8.5<\/strong>, <strong>ISO 3171<\/strong>, and <strong>ASTM D4177<\/strong> standards, ensuring every sample accurately represents the process fluid composition.\n\nWhat Is a Closed Loop Sampling System?\nA closed loop sampling system captures process fluid samples without exposing operators or the environment to hazardous materials. Unlike open sampling methods, our systems maintain a sealed pathway from the process point to the sample container, eliminating VOC emissions, protecting personnel from toxic exposure, and preventing sample contamination from atmospheric moisture or air ingress.\n\nFour Types of Closed Loop Sampling Systems We Manufacture\n\n<strong>Closed Loop Liquid Sampling System:<\/strong> Designed for oil, refined products, chemicals, and liquefied gases. Features automatic purge cycles, variable volume sample cylinders (500ml to 2000ml), and optional online analyzers integration.\n<strong>Closed Loop Gas Sampling System:<\/strong> For natural gas, LPG, flare gas, and biogas applications. Includes helium leak-tested components, cylinder filling stations, and composite samplers for time-proportional sampling.\n<strong>Vapor Recovery Sampling Unit (VRSU):<\/strong> Captures volatile emissions during loading\/unloading operations. Meets EPA and EU environmental regulations for terminal and depot applications.\n<strong>Composite \/ Online Sampler:<\/strong> Automated grab or flow-proportional sampling with programmable intervals. Ideal for custody transfer applications where representative averaging is critical.\n\n\nKey Advantages of Wanan Closed Loop Sampling Systems\n\n<strong>Safety First Design:<\/strong> Full compliance with ATEX, IECEx Zone 1\/Zone 2 classifications for explosive atmosphere installations\n<strong>Sample Integrity:<\/strong> Maintains sample phase, pressure, and composition from process point to laboratory analysis\n<strong>Modular Configuration:<\/strong> Customizable panels, probes, cylinders, and controllers for any application requirement\n<strong>Global Compliance:<\/strong> Certified for API, ISO, GOST-R, and regional standards across 50+ countries\n\n\nBrowse our complete range of <a href=\"\/ar\/product-category\/%d9%86%d8%b8%d8%a7%d9%85-%d8%a3%d8%ae%d8%b0-%d8%a7%d9%84%d8%b9%d9%8a%d9%86%d8%a7%d8%aa-%d8%a7%d9%84%d9%81%d8%a6%d9%88%d9%8a\/\">sampling system products<\/a> or contact our engineering team for custom configuration assistance.\n<\/div>","link":"https:\/\/wanantec.com\/ar\/product-category\/%d9%86%d8%b8%d8%a7%d9%85-%d8%a3%d8%ae%d8%b0-%d8%a7%d9%84%d8%b9%d9%8a%d9%86%d8%a7%d8%aa-%d8%a7%d9%84%d9%81%d8%a6%d9%88%d9%8a\/","name":"\u0646\u0638\u0627\u0645 \u0623\u062e\u0630 \u0627\u0644\u0639\u064a\u0646\u0627\u062a","slug":"%d9%86%d8%b8%d8%a7%d9%85-%d8%a3%d8%ae%d8%b0-%d8%a7%d9%84%d8%b9%d9%8a%d9%86%d8%a7%d8%aa-%d8%a7%d9%84%d9%81%d8%a6%d9%88%d9%8a","taxonomy":"product_cat","parent":0,"meta":[],"acf":[],"_links":{"self":[{"href":"https:\/\/wanantec.com\/ar\/wp-json\/wp\/v2\/product_cat\/49","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wanantec.com\/ar\/wp-json\/wp\/v2\/product_cat"}],"about":[{"href":"https:\/\/wanantec.com\/ar\/wp-json\/wp\/v2\/taxonomies\/product_cat"}],"wp:post_type":[{"href":"https:\/\/wanantec.com\/ar\/wp-json\/wp\/v2\/product?product_cat=49"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
